Defining the serial line communication parameters for navigation sensors and external devices
Serial line communication with external devices is important for the TV80 system. All serial line communication is based on specific transmission parameters. These parameters must be defined at each end of the line, and they must be set up identical. By means of the Serial Port Setup dialog box, you can define these parameters manually to match fixed parameters on the peripheral device.
Prerequisites
•  The TV80 software is installed on the Processor Unit.
•  The new device is physically connected to the Processor Unit using a serial cable.
•  The communication parameters required for the device interface are known.
Procedure
1 Open the Setup menu.
2 On the Setup menu, select Installation.

Observe that the Installation dialog box opens.
3 Observe the I/O Setup page on the right side of the Installation dialog box.
Every interface is presented as a small "block diagram".
4 In the relevant block diagram, select the serial port icon.

5 Make the necessary adjustments.
The communication parameters defined for NMEA 0183 are:
•  Baud rate: 4800 bit/s
•  Data bits: 8
•  ParityEven
•  Stop bits: 1
Some instruments may provide other parameters and/or options. You must always check the relevant technical documentation supplied by the manufacturer.
6 Select OK to save the selected settings and close the dialog box.
